In a driver seat display D1, a menu including drive mode, advanced driver assistance systems (ADAS), air conditioning, and volume is displayed, and in a state in which there is no displayed item in a passenger seat display D2, a knob 200 is moved from under the driver seat display D1 to under the passenger seat display D2.

As the knob 200 is moved from under the driver seat display D1 to under the passenger seat display D2, available functions are changed, for example, in the driver seat display D1, functions, such as the ADAS and the drive mode, which are directly related to driving, may be manipulated, and in the passenger seat display D2, restricted functions, such as interior lamp, air conditioning, and volume, which are relatively less related to the driving, may be performed.

The processor 130 controls function control tabs displayed on the driver seat display D1 and the passenger seat display D2 in consideration of movement information of the knob 200.

As will be described below, as the knob 200 is manipulated to be rotated or pressed under a specific function control tab area or on the specific function control tab area, setting of a specific function is adjusted.

FIG. 3 is a view illustrating a change in user interface (UI) of the display according to one embodiment of the present invention.

A big screen display D is divided into a plurality of areas and moves in a direction from the driver seat to the passenger seat.

As the big screen display D is moved, a position of the knob may be changed, or as the position of the knob is changed, a position of the big screen display D may be changed.

As the big screen display D is moved, information and the UI displayed on the big screen display D are changed, and for example, a cluster and audio video navigation (AVN) are displayed on the big screen display D in front of the driver seat, and a mini-cluster and an AVN 3 screen are displayed thereon in front of the passenger seat.

Movement of the knob 200 occurs within a mechanically limited area between the driver seat and the passenger seat, or the knob 200 is detachably attached to a center fascia, and the processor 130 controls the information and the UI of the big screen display D in consideration of a state in which the knob 200 is spatially moved.

FIG. 4A and FIG. 4B are set of views illustrating the display that is controlled when the knob is removed according to one embodiment of the present invention.

As the knob 200 positioned on the console under the display D is removed from the console, the processor 130 moves the display D in consideration of the removal and a movement direction of the knob 200. Referring to FIG. 4A and FIG. 4B, as the knob 200 is removed from the console and moved in the direction from the driver seat to the passenger seat, a position of the display D is adjusted so that the display D is viewed from both of the driver seat and the passenger seat.

When the knob 200 is moved from the driver seat to the passenger seat, a personalized screen related to a passenger is displayed on the display D moved to the passenger seat, and a driving related screen is displayed as a head-up display (HUD) on a windshield in front of the driver seat.

When the knob 200 is moved from the passenger seat to the driver seat, the driving related screen is displayed on the display D moved to the driver seat, and the personalized screen related to the passenger of the passenger seat is displayed on the windshield in front of the passenger seat. In this case, in a case in which driving is hindered by displaying information on the windshield in front of the passenger seat, the display of the personalized screen related to the passenger of the passenger seat is turned off.

FIG. 5A and FIG. 5B are set of views illustrating the display D that is tilted when the knob is removed according to one embodiment of the present invention.

As the knob 200 positioned on the console under the display D is removed from the console, the display D is tilted in consideration of a position of the knob 200.

In a case in which a passenger in a rear seat takes the knob 200 (manipulation system), the display D is tilted so that a screen of the display D is easily viewed from the passenger having the knob in the rear seat.

In relation to a position of the knob in the vehicle, position information of the knob is checked using ultra wide band (UWB) technology.

In order to provide a local based service (LBS), technologies such as a global positioning system (GPS), Wi-Fi, and Bluetooth are used, but it is difficult to precisely check a position. However, the UWB (6 to 8 GHz and 500 MHz or higher bandwidth) has advantages of a wide frequency band, lower power communication, and high accuracy of about several tens of centimeters.

Position tracking technologies based on a GPS and mobile communication networks according to the related art respectively have error ranges of 5 to 50 m and 50 to 200 m, and in the case of the GPS, a problem may occur to catch signals transmitted from satellites in urban buildings.

In the case of the Wi-Fi, position tracking is performable with a low cost, but since a use frequency band is narrow, in a case in which there are many position tracking targets, a channel division limitation may occur. In addition, a mobile terminal may be disconnected from a fixed Wi-Fi access point (AP).

In the case of Bluetooth, it is possible to arrange a plurality of sensors at a low cost, however, since a communication latency is large, the Bluetooth is not suitable for tracking a position in a dynamic environment in real time.

Unlike Wi-Fi and Bluetooth, the UWB uses a wide frequency band and may transmit a large amount of information at a high transmission speed with low power.

Position tracking using the UWB technology has advantages of a low error rate of about 20 centimeters, a high transmission rate for an obstacle, and not being affected by another signal such as a Wi-Fi signal.
